' Y EVEN-'FEED ACCELERATOR. l i

, i Application filed July 23,

To all whom it may concern:

`Be it known that I, ELDIE I?. CoNwELL, a citizen of the UnitedStates,residing at Allerton, in the county of Wayne and State of Iowa, haveinvented certain new and useful Iijnprovements in Even-FeedAccelerators, of which the/following is a specification. f

This invention relates to even feed accelerators, and it consists in thenovel fea-- tures hereinafter described andclaimed.Y

An object of the invention is to provide an even feed accelerator ofsimple and durable structure, and adapted tobe connected; with thebutteriiy valve of acarburetor of an automobile engine, and having meansadapted to be positioned upon the floor board of an automobile machine,and which may be operated by the foot of the driver of the machine, toaccelerate or regulate the How of mixture from the carburetor to theintake manifold of the engine.

With the above object in view, the structure includes a bracket memberadapted to be applied to thel engine, and having. a shaft journalledtherein, and Which passes through the dash board of the automobilemachine. The shaft is provided at its rear end with an angularlydisposed arm, upon which a foot piece is mounted. The said men'iber isadapted to rest upon the floor board of the body ofv the automobilemachine. The said shaft also carries, at a` point between-its ends, anarm having any angularly disposed extremity, which 1s con-j nected withthe pull rod of the butterfly valve. Links are connected Withsaid rodand also connected with the regular lever means for operatingv the saidrod and the valve.

In the accompanying drawing:

Figure l is a top plan view of the accelerator. Figure 2 is a sideelevational View of the same. v

Figure 3 is a transverse sectional-view, through the upper portion of anenglne ofan automobile machine, and showingk the accelerator applied. l

As illustrated in the accompanying drawings, the accelerator comprises abracket l having angularly disposed end portlons and intermediate archedportions 2. The end portions 3 of the bracket 1 are secured to theengine by means of bolts 3. A shaft 4 is journalled at one end in thebracket l,

l member having 1924.A serial No. 727,739.

and passes transversely through the dash board `5 of theautomobilemachine, and is provided at its rear end with an angularlydisposed arm. A foot piece 7 is hinge jointed upon the arm 6, and itsrear end is adapted to rest upon the upper surface of the floor `boardSof the automobile machine.l

The shaft 4 is providedI at a point between its ends with an arm 9,having an angularly disposedl extremity 10. The extremity 10 ispivotally connected with the pull rod 11,'

which in turn is operatively connected with the butteriiy valve stem 12,in aj usualmanner. Links 13 are also connected with the arm 9 and rod 11and may be connected with the regula-r hand operated lever on theautomobile (not shown), and whereby the valve may be operated by hand.Itis apparent that when the driver of an automobile machine places hisfooton the lfloor beside the foot piece 7 and moves it to the left, theshaft let is turned, whereby the arm 9 is swung and the rod ll isymovedlongitudinally, whereby the valve stem 12 is turned, andconsequently the passageway throughvthe manifold pipe is increased ordiminished, and a greater or smaller supply of the mixture may pass fromthe ,carburetor, into the intake manifold of the engine. Thus, theoperation of the engine may be accelerated by the driver. of theautomobile machinewho may use his foot, instead of his hand, to controlthe operation of the engine.

The foot piece 7' is instantly turned up against coil box out of the Waywhenever the fioor boards need to be removed.

When the boards are replaced the foot piece 7 is returned to itsoriginal position.

I-Iaving described the invention, what is claimed is: y i y l. Anaccelerator kcomprising a bracket angularly disposed end portions andprovided with an arched interlnediate portion, a shaft jolilrnalled inthe bracket member and having an angularly disposed arm, a. foot piecehinge jointed upon the shaft, a spring connecting the second mentionedarm with the arched portion of the bracket, the last mentioned armhaving an angularly disposed` extremity, adapted to be pivotallyconnected with the pull rod of the butterfly valve controlling mechanismof the automobile machine.

2. An accelerator comprising a bracket,

upon the arm, a second arm mounted f having unguiarly disposed endportions and nn intermediate arched portion@ shaft journaiied upon thebracket member, and heving at its rear end an singularly disposed arm,2L foot piece hinge jointed upon the arm and adapted to rest upon theiioor of the automobile machine, u second arm depending from said shaftl und provided at its lower end with an angularly disposed ex trelnity,adapted to be connected with the 10 end with the intermediate portionot' the last 15 mentioned arm.
